Hi, is it possible to use SQL SERVER 2008r2 as my database in my php application programs.?because i only experience using the wampserver and mysql as my database...if php can talk to sql server can you help me please how can i use sql server as my database.

PDO also has the advantage of a "common interface" for different servers so provided you stick to standard SQL and don't use any vendor specific/only SQL then you would be able to easily migrate to a different server at a later date
